Hmmm, who should we cc? Or is it bugzilla.kernel.org time?

Thanks for all the (sleeping) penguins.

But I don't have ACPI compiled in (as the BIOS is APM-only). Does it matter?

Finally, I debugged it today. The problem is in PNP BIOS. pnp_bus_suspend()
calls pnp_stop_dev() for the device if the device can be disabled according
to pnp_can_disable(). The problem is that pnpbios_disable_resources()
returns -EPERM if the device is not dynamic (!pnpbios_is_dynamic()) but
insert_device() happily sets PNP_DISABLE capability/flag even if the device
is not dynamic. So we try to disable non-dynamic devices which will fail.
This patch prevents insert_device() from setting PNP_DISABLE if the device is
not dynamic and fixes suspend on my system.
